ChemSep Features

Column Simulations Made Easy

Whether used stand-alone or embedded in a flowsheet, ChemSep provides you with a robust column simulator
that does not require you to supply initial guesses. Our intuitive interface runs within all CAPE-OPEN compliant
commercial process design software allowing a wide variety of column configurations and specifications.
The easy to use interface enables you to solve your separations problems in minutes.

Models Actual Column Performance

ChemSep is a column simulator for distillation, absorption, and extraction operations.
Choose the classic equilibrium stage column model and then switch to the nonequilibrium
(rate-based) model for more accurate descriptions of actual column performance.
ChemSep has its own libraries with an extensive set of capacity and mass transfer performance
parameters for trays and packings. Together with the thermodynamic and physical property
packages ChemSep offers a wide range of applications is covered.

Quick Engineering

Inspect the results of your column configuration instantaneously with predefined plots so that you
can engineer the best line-up using rigorous simulations. Quickly find the specifications that deliver
optimal column performance and use vendor tools to match capacity and required packed bed or trays to
obtain the most economical solution. ChemSep can then directly export to requisition data sheets.

Industrial Strength Solver

ChemSep has been tested with many industrial columns such as demethanizers, debutanizers,
refluxed absorbers, azeotropic and extractive distillation; all solve robustly without requiring the
user to provide any initial guesses. Computation speed remains high even when including tens or
hundreds of compounds. An extensive set of examples is available online.

Versatile and Customizable

Engineers do not have to worry about units conversions; they are built-in. Results can be exported
into a range of formats including a spreadsheet layout that the you can design. Graphs can be stored and
re-applied to each new simulation. Populate your toolbar with your favourite actions.

Comprehensive and In-depth Modelling

Simulate columns by means of efficiencies, or better, by means of detailed rate-based models for
trays and packings to compute actual column performance. With ChemSep's design mode the simulator
runs automatically and column diameters are set by means of the specified fraction of flood.
ChemSep has a large database with validated model parameters for all standard column internals
including modern high capacity packings from Sulzer, Koch-Glitsch, Montz, and Raschig.

Test Drive for Free

Test-drive the equilibrium column model and convince yourself with the free ChemSep LITE with up
to 40 components and 300 equilibrium stages using a database covering 400+ chemicals.
Run ChemSep standalone or inside a flowsheet simulator.
